The serial interface consists of serial clock SCLK, serial data SDIN, D/C#, CS#. In this mode, D0 acts as
SCLK, D1 acts as SDIN. For the unused data pins, D2 should be left open. D3 to D7, E and R/W pins
can be connected to external ground.
SDIN is shifted into an 8-bit shift register on every rising edge of SCLK in the order of D
sampled on every eighth clock and the data byte in the shift register is written to the Display Data RAM or
command register in the same clock.
During data writing, an additional NOP command should be inserted before the CS# goes high (Refer to
Figure 7.
